Detailed Description
An input device according to an aspect of the present disclosure includes: a rotating member that rotates around a predetermined rotation axis; and a mover formed with a convex portion protruding toward an inner peripheral surface of the rotary member and moving in a direction different from a rotation direction of the rotary member in accordance with rotation of the rotary member, the rotary member having a 1 st protrusion and a 2 nd protrusion protruding from the inner peripheral surface toward the mover, the convex portion of the mover being formed obliquely with respect to the predetermined rotation axis and being disposed between the 1 st protrusion and the 2 nd protrusion.
According to the present invention, the convex portion of the moving member is formed obliquely with respect to the predetermined rotation axis, and is disposed between the 1 st and 2 nd protrusions of the rotating member. Thus, when the rotating member is rotated in the 1 st direction, the 1 st projection presses the convex portion, and the moving element moves in the 3 rd direction. At this time, the 1 st projection receives the load from the convex portion, but the 2 nd projection does not receive the load from the convex portion. On the other hand, when the rotating member is rotated in the 2 nd direction (the direction opposite to the 1 st direction), the 2 nd protrusion presses the convex portion, and the moving element moves in the 4 th direction (the direction opposite to the 3 rd direction). At this time, the 2 nd projection receives the load from the convex portion, but the 1 st projection does not receive the load from the convex portion. Therefore, only either one of the 1 st projection and the 2 nd projection receives a load from the convex portion according to the rotation direction of the rotary member, and therefore, the durability of the rotary member can be improved.
For example, the moving member may be configured to move in a direction substantially parallel to the predetermined rotation axis in accordance with rotation of the rotating member.
According to the present invention, the moving element can be moved in a direction substantially parallel to the predetermined rotation axis by rotating the rotating member.
For example, a straight line connecting the 1 st projection and the 2 nd projection may be inclined with respect to the predetermined rotation axis.
According to the present invention, for example, when the rotary member is resin-molded, the occurrence of a dead corner can be suppressed. Further, the distance between the 1 st projection and the 2 nd projection can be kept small, and the rotating member can be downsized.
For example, a portion of the 1 st projection that contacts the convex portion and a portion of the 2 nd projection that contacts the convex portion may be formed in spherical shapes.
According to the present invention, the 1 st projection and the 2 nd projection can be in point contact with the convex portion, respectively. As a result, the frictional resistance when the 1 st projection and the 2 nd projection slide on the convex portion can be reduced, and the operational feeling of the rotary member can be improved.
For example, the 1 st protrusion may include: a 1 st column member protruding from the inner peripheral surface of the rotating member toward the mover; and a 1 st ball member formed at a tip end portion of the 1 st column member and having a diameter longer than that of the 1 st column member, the 2 nd protrusion portion having: a 2 nd column member protruding from the inner peripheral surface of the rotating member toward the mover; and a 2 nd ball member formed at a tip end portion of the 2 nd column member, and having a diameter longer than that of the 2 nd column member.
According to the present invention, for example, when the rotary member is resin-molded, the mold can be easily operated.
For example, the protruding portion may be formed so as to be tapered toward both end portions of the protruding portion in a direction inclined with respect to the predetermined rotation axis when viewed from a protruding direction of the protruding portion.
According to the present aspect, the distance between the 1 st projection and the 2 nd projection varies with the rotation of the rotating member when viewed from the projection direction of the convex portion. Thus, by making both end portions of the convex portion tapered, the 1 st and 2 nd projecting portions can be stably slid on the convex portion from one end portion to the other end portion of the convex portion. As a result, the movable region of the rotary member can be increased.
For example, the protruding portion may be formed such that, when viewed from a direction orthogonal to the protruding direction of the protruding portion, a protruding length thereof gradually decreases from a central portion of the protruding portion toward both end portions thereof in a direction inclined with respect to the predetermined rotation axis.
According to the present invention, the 1 st projection and the 2 nd projection draw circular arc-shaped trajectories as the rotating member rotates. Thus, the projection length of the convex portion gradually decreases from the central portion of the convex portion toward the both end portions, whereby the 1 st projection portion and the 2 nd projection portion can be stably slid on the convex portion from the one end portion to the other end portion of the convex portion. As a result, the movable region of the rotary member can be increased.
The embodiments are described below in detail with reference to the drawings.
The embodiments described below are general or specific examples. The numerical values, shapes, materials, and constituent elements shown in the following embodiments, the arrangement positions and connection forms of the constituent elements, the steps, the order of the steps, and the like are examples, and the present disclosure is not limited thereto.

[ 1 ] outline of input device
First, an outline of the input device 2 according to the embodiment will be described with reference to fig. 1 and 2. Fig. 1 is a diagram showing an example of a vehicle 4 on which an input device 2 according to the embodiment is mounted. Fig. 2 is a diagram showing an external appearance of the input device 2 according to the embodiment.
As shown in fig. 1, a steering column 6 is mounted on a driver's seat of the vehicle 4. The steering column 6 is disposed between the steering wheel 8 and the instrument panel 10. The vehicle 4 is, for example, a general passenger car, a bus, or a truck. The vehicle 4 is not limited to an automobile, and may be, for example, a construction machine, an agricultural machine, or the like.
The steering column 6 supports the steering rod 12 and the wiper rod 14 so as to be tiltable. As shown in fig. 1, for example, in the case where the vehicle 4 is a right-handed vehicle, the steering rod 12 is disposed on the right side as viewed from the driver, and the wiper rod 14 is disposed on the left side as viewed from the driver.
The steering lever 12 is a combination switch lever having, for example, a) a turn signal switch for flashing a turn signal, b) a light switch for switching on and off headlights, small lights (vehicle width lights), fog lights, and tail lights, c) a flashing switch for flashing the headlights, and d) a dimmer switch for switching between a high beam and a low beam of the headlights.
As shown in fig. 2, the steering lever 12 has a lever main body 16 and the input device 2. The rod main body 16 is formed in a cylindrical shape. The input device 2 has a pair of rotary switches 18, 20. The pair of rotary switches 18 and 20 are disposed at intervals in the longitudinal direction of the lever main body 16. The rotary switch 18 is, for example, a light switch for switching on and off of a headlight, a small light, and a tail light. The rotary switch 20 is, for example, a light switch for switching on and off of a fog lamp.

[ 2 ] Structure of input device
The configuration of the input device 2 according to the embodiment will be described with reference to fig. 2 to 8. Fig. 3 is a perspective view showing the input device 2 according to the embodiment. Fig. 4 is a perspective view showing the input device 2 of the embodiment in a state where the outer knob 22 and the rotor member 24 are omitted. Fig. 5 is a plan view showing the input device 2 of the embodiment in a state where the outer knob 22 and the rotor member 24 are omitted. Fig. 6 is an exploded perspective view showing the motion conversion mechanism 32 according to the embodiment. Fig. 7 is an exploded perspective view showing the motion conversion mechanism 32 according to the embodiment in a state viewed from a different angle from that in fig. 6. Fig. 8 is a diagram for explaining the relationship between the mold opening direction and the respective positions of the 1 st projection 50 (50A, 50B) and the 2 nd projection 52 (52A, 52B) at the time of molding the rotary member 26 (26A, 26B) of the resin molding embodiment.
In each of fig. 3 and subsequent drawings, the width direction of the input device 2 is defined as the X-axis direction, the depth direction of the input device 2 is defined as the Y-axis direction, and the height direction of the input device 2 is defined as the Z-axis direction.
The pair of rotary switches 18, 20 of the input device 2 have the same structure. Therefore, only the structure of the rotary switch 20 in the input device 2 will be described below.
As shown in fig. 2 to 4, the rotary switch 20 of the input device 2 includes an outer knob 22, a rotor member 24, a rotary member 26, a base plate 28, a mover 30, and a motion conversion mechanism 32.
As shown in fig. 2 and 3, the outer knob 22 is formed in a cylindrical shape and is disposed on the outermost side in the radial direction of the steering rod 12. The outer knob 22 is rotatably supported by the lever main body 16. More specifically, the outer knob 22 is rotatable about a predetermined rotation axis 34 with respect to the lever main body 16 in a 1 st direction (a direction indicated by an arrow P in fig. 2 and 3), and is rotatable in a 2 nd direction (a direction indicated by an arrow Q in fig. 2 and 3) which is a direction opposite to the 1 st direction. As shown in fig. 3 and 4, the predetermined rotation axis 34 is an imaginary straight line passing through the radial center of the lever main body 16 and extending in the longitudinal direction (Y-axis direction) of the lever main body 16.
For example, when the driver manually rotates the outer knob 22 in the 1 st direction, the fog lamp of the vehicle 4 is turned on. On the other hand, when the driver manually rotates the outer knob 22 in the 2 nd direction, the fog lamp of the vehicle 4 is turned off.
As shown in fig. 3, the rotor member 24 is a member for supporting the rotary member 26. The rotor member 24 is formed in a cylindrical shape and attached to the inner peripheral surface of the outer knob 22. The rotor member 24 is formed with a positioning slit 36. The rotor member 24 rotates integrally with the outer knob 22 about a predetermined rotation axis 34.
As shown in fig. 3, the rotary member 26 is made of, for example, resin and supported on the inner peripheral surface of the rotor member 24. As shown in fig. 4 to 7, the rotary member 26 includes a main body portion 38 and an engagement portion 40.
The main body 38 is formed in an arc-shaped cross section. The engaging portion 40 protrudes from the outer peripheral surface of the body portion 38 toward the rotor member 24, and engages with the slit 36 of the rotor member 24. Thereby, the body portion 38 is positioned with respect to the rotor member 24, and rotates integrally with the rotor member 24 and the outer knob 22. More specifically, the main body portion 38 (the rotary member 26) rotates in the 1 st direction (the direction indicated by the arrow P in fig. 3 to 5) and the 2 nd direction (the direction indicated by the arrow Q in fig. 3 to 5) about the predetermined rotation axis 34 with respect to the mover 30.
The base plate 28 is disposed inside the lever main body 16. A plurality of electrode pads 42 are formed on the substrate 28. The plurality of electrode pads 42 are electrically connected to various electrical components (not shown) such as a turn signal lamp, a headlight, a small lamp, a fog lamp, and a tail lamp mounted on the vehicle 4 via electric wires (not shown), respectively.
The moving element 30 is disposed between the rotating member 26 and the base plate 28. The mover 30 has a mover body 44 and a plurality of contact members 46. The moving element body 44 is movably supported by a guide member (not shown) disposed inside the lever body 16. The moving element body 44 linearly moves along the guide member substantially in parallel with the predetermined rotation axis 34 (i.e., in a direction different from the rotation direction of the rotary member 26). More specifically, as shown in fig. 5, the mover body 44 (mover 30) is linearly moved along the predetermined rotation axis 34 with respect to the rotary member 26 in a 3 rd direction (a direction indicated by an arrow U in fig. 5) and a 4 th direction (a direction indicated by an arrow V in fig. 5) which is a direction opposite to the 3 rd direction. In the present specification, "substantially parallel" is a concept including not only perfect parallel but also a range of, for example, ± 10 ° with respect to the perfect parallel direction.
The plurality of contact members 46 are attached to a surface of the mover body 44 facing the base plate 28. The plurality of contact members 46 are electrically contacted with the plurality of electrode pads 42 formed on the substrate 28, respectively. The electrical connection relationship of the plurality of contact members 46 and the plurality of electrode pads 42 varies according to the moving direction of the moving member 30. Thus, for example, when the mover 30 moves linearly in the 3 rd direction, the fog light of the vehicle 4 is turned on, and when the mover 30 moves linearly in the 4 th direction, the fog light of the vehicle 4 is turned off.
The motion conversion mechanism 32 is a mechanism for converting the rotation of the rotary member 26 into the linear movement of the mover 30. As shown in fig. 6 and 7, the motion conversion mechanism 32 includes a convex portion 48 formed on the moving element 30, and a 1 st projection 50 and a 2 nd projection 52 formed on the rotary member 26.
The convex portion 48 is formed to protrude from a surface of the mover body 44 facing the rotary member 26 toward the inner peripheral surface of the body portion 38 of the rotary member 26. As shown in fig. 5, the convex portion 48 is formed obliquely with respect to the predetermined rotation axis 34 and is disposed between the 1 st projection 50 and the 2 nd projection 52 of the rotation member 26. The convex portion 48 is formed in a substantially arcuate shape in cross section (japanese kamaboko shape), and has a top surface 48a, a 1 st side surface 48b, and a 2 nd side surface 48c located on the opposite side of the 1 st side surface 48 b.
As shown in fig. 6, the top surface 48a of the convex portion 48 is curved in a circular arc shape along a direction inclined with respect to the predetermined rotation axis 34. That is, the protruding portion 48 is formed such that the protruding length gradually decreases from the central portion toward both end portions of the protruding portion 48 in a direction inclined with respect to the predetermined rotation axis 34 when viewed from a direction orthogonal to the protruding direction of the protruding portion 48 (a direction perpendicular to the 1 st side surface 48b and the 2 nd side surface 48 c).
As shown in fig. 5, the convex portion 48 is formed so as to be tapered toward both end portions of the convex portion 48 in a direction inclined with respect to the predetermined rotation axis 34 when viewed from the projecting direction (Z-axis direction) of the convex portion 48.
As shown in fig. 6 and 7, the 1 st projecting portion 50 projects from the inner peripheral surface of the main body portion 38 toward the moving member 30. The 1 st projection 50 has a 1 st column member 54 and a 1 st ball member 56. The 1 st column member 54 is formed in a substantially cylindrical shape, and protrudes from the inner peripheral surface of the body portion 38 toward the mover 30. The 1 st ball member 56 is formed into a spherical shape and is disposed at the tip end of the 1 st column member 54. The diameter of the 1 st ball member 56 is longer than the diameter of the 1 st column member 54. The 1 st ball member 56 is disposed to face the 1 st side surface 48b of the convex portion 48 of the mover 30. When the rotary member 26 rotates in the 1 st direction, the 1 st ball member 56 contacts (makes point contact with) the 1 st side surface 48b of the convex portion 48 of the mover 30. That is, the portion (the 1 st ball member 56) of the 1 st projection 50 that contacts the convex portion 48 is formed in a spherical shape.
As shown in fig. 6 and 7, the 2 nd projecting portion 52 projects from the inner peripheral surface of the main body portion 38 toward the moving member 30. The 2 nd protrusion 52 has a 2 nd column member 58 and a 2 nd ball member 60. The 2 nd pillar member 58 is formed in a substantially cylindrical shape, and protrudes from the inner peripheral surface of the body portion 38 toward the moving element 30. The 2 nd ball member 60 is formed into a spherical shape and is disposed at the tip end of the 2 nd column member 58. The diameter of the 2 nd ball member 60 is longer than the diameter of the 2 nd column member 58. The 2 nd ball member 60 is disposed opposite to the 2 nd side surface 48c of the convex portion 48 of the mover 30. When the rotary member 26 rotates in the 2 nd direction, the 2 nd ball member 60 contacts (makes point contact with) the 2 nd side surface 48c of the convex portion 48 of the mover 30. That is, the portion (the 2 nd ball member 60) of the 2 nd protrusion 52 that contacts the convex portion 48 is formed in a spherical shape.
As shown in fig. 5, a straight line 62 connecting the 1 st projection 50 and the 2 nd projection 52 is inclined with respect to the predetermined rotation axis 34.
Here, the relationship between the mold opening direction and the respective positions of the 1 st projection 50 (50A, 50B) and the 2 nd projection 52 (52A, 52B) when the rotary member 26 (26A, 26B) is resin-molded will be described with reference to fig. 8. Hereinafter, a case where the mold opening direction is substantially parallel to the predetermined rotation axis 34 will be described.
As shown in fig. 8 (a), in the rotary member 26 of the embodiment, a straight line 62 connecting the 1 st projection 50 and the 2 nd projection 52 is inclined with respect to the predetermined rotation axis 34. In this case, when the mold is opened, a dead corner portion that cannot be released does not occur.
As shown in fig. 8 (b), in the rotary member 26A of comparative example 1, the straight line 62A connecting the 1 st projection 50A and the 2 nd projection 52A is parallel to the predetermined rotation axis 34. In this case, when the mold is opened, the blind spot 64 is generated, which cannot be removed.
As shown in fig. 8 (c), in the rotary member 26B of comparative example 2, the straight line 62B connecting the 1 st projection 50B and the 2 nd projection 52B is perpendicular to the predetermined rotation axis 34. In this case, when the mold is opened, a dead corner portion that cannot be released does not occur. However, in this case, the distance D1 in the direction perpendicular to the predetermined rotation axis 34 between the 1 st projection 50B and the 2 nd projection 52B is longer than the structure of fig. 8 (a) (the distance in the direction perpendicular to the predetermined rotation axis 34 between the 1 st projection 50 and the 2 nd projection 52), and the rotary member 26B is increased in size accordingly.
From the above, as shown in fig. 8 (a), it is preferable that the straight line 62 connecting the 1 st projection 50 and the 2 nd projection 52 is inclined with respect to the predetermined rotation axis 34. This can suppress the occurrence of a dead-angled portion when the rotary member 26 is resin-molded. Further, the distance between the 1 st projection 50 and the 2 nd projection 52 can be kept small, and the rotary member 26 can be made compact.
[ 3 ] motion of motion conversion mechanism ]
The operation of the motion conversion mechanism 32 will be described with reference to fig. 9 to 12. Fig. 9 is a plan view showing the motion conversion mechanism 32 according to the embodiment in the case of rotating the rotary member 26 in the 1 st direction. Fig. 10 is a sectional view of the motion conversion mechanism 32 of the embodiment taken along line X-X of fig. 9. Fig. 11 is a plan view showing the motion conversion mechanism 32 according to the embodiment in the case of rotating the rotary member 26 in the 2 nd direction. Fig. 12 is a sectional view of the motion conversion mechanism 32 of the embodiment taken along line XII-XII in fig. 11.
First, as shown in fig. 9, a case where the rotating member 26 is rotated in the 1 st direction (the direction indicated by the arrow P in fig. 9) will be described. In this case, as shown in fig. 10, the 1 st ball member 56 of the 1 st projection 50 of the rotary member 26 slides on the 1 st side surface 48b of the convex portion 48 from one end portion toward the other end portion of the convex portion 48 in a direction inclined with respect to the predetermined rotation axis 34 (a direction perpendicular to the paper surface of fig. 10) while pressing the 1 st side surface 48b of the convex portion 48 of the mover 30. The mover 30 is linearly moved in the 3 rd direction (the direction indicated by the arrow U in fig. 9) by receiving the pressing force of the 1 st ball member 56 from the 1 st protrusion 50. Further, since the 1 st ball member 56 is in point contact with the 1 st side surface 48b of the projection 48, the frictional resistance when the 1 st ball member 56 slides on the 1 st side surface 48b of the projection 48 can be reduced, and the operational feeling of the rotary member 26 can be improved.
At this time, a gap (not shown) is formed between the 2 nd ball member 60 of the 2 nd protrusion 52 and the 2 nd side surface 48c of the convex portion 48. Therefore, when the rotary member 26 is rotated in the 1 st direction, the 1 st ball member 56 of the 1 st projection 50 receives a load from the convex portion 48, but the 2 nd ball member 60 of the 2 nd projection 52 does not receive a load from the convex portion 48.
Next, as shown in fig. 11, a case where the rotary member 26 is rotated in the 2 nd direction (the direction indicated by the arrow Q in fig. 11) will be described. In this case, as shown in fig. 12, the 2 nd ball member 60 of the 2 nd projecting portion 52 of the rotary member 26 slides on the 2 nd side surface 48c of the projecting portion 48 from the other end portion toward the one end portion of the projecting portion 48 in a direction inclined with respect to the predetermined rotation axis 34 (a direction perpendicular to the paper surface of fig. 12) while pressing the 2 nd side surface 48c of the projecting portion 48 of the moving member 30. The mover 30 is linearly moved in the 4 th direction (the direction indicated by the arrow V in fig. 11) by receiving the pressing force of the 2 nd ball member 60 from the 2 nd protrusion 52. Further, since the 2 nd ball member 60 is in point contact with the 2 nd side surface 48c of the convex portion 48, the frictional resistance when the 2 nd ball member 60 slides on the 2 nd side surface 48c of the convex portion 48 can be reduced, and the operational feeling of the rotary member 26 can be improved.
At this time, a gap (not shown) is formed between the 1 st ball member 56 of the 1 st projection 50 and the 1 st side surface 48b of the convex portion 48. Thus, when the rotary member 26 is rotated in the 2 nd direction, the 2 nd ball member 60 of the 2 nd projection 52 receives a load from the convex portion 48, but the 1 st ball member 56 of the 1 st projection 50 does not receive a load from the convex portion 48.
As described above, the mover 30 linearly moves in a direction substantially parallel to the predetermined rotation axis 34 in accordance with the rotation of the rotary member 26.
[ 4. Effect ]
The structure of the motion conversion mechanism 100 of the comparative example will be described, and the effects obtained by the input device 2 of the embodiment will be described. Fig. 13 is a schematic cross-sectional view of a motion conversion mechanism 100 of a comparative example.
As shown in fig. 13, the motion conversion mechanism 100 of the comparative example includes a columnar protrusion 104 protruding from the inner peripheral surface of the rotary member 102 and a groove 108 formed in the moving member 106. The groove 108 is formed obliquely to a predetermined rotation axis 110 of the rotary member 102. The protrusion 104 is slidably engaged with the groove 108, and is in contact (line contact) with the 1 st inner surface 108a and the 2 nd inner surface 108b (surfaces facing the 1 st inner surface 108 a) of the groove 108.
When the rotary member 102 is rotated in the 1 st direction (the direction indicated by the arrow P in fig. 13), the protrusion 104 slides on the 1 st inner surface 108a of the groove 108 from one end portion to the other end portion of the groove 108 while pressing the 1 st inner surface 108a of the groove 108. The moving member 106 is linearly moved in the 3 rd direction (the direction indicated by the arrow U in fig. 13) by receiving the pressing force from the protrusion 104.
When the rotary member 102 is rotated in the 2 nd direction (the direction indicated by the arrow Q in fig. 13) which is the direction opposite to the 1 st direction, the protrusion 104 slides on the 2 nd inner surface 108b of the groove 108 from the other end portion toward the one end portion of the groove 108 while pressing the 2 nd inner surface 108b of the groove 108. The moving member 106 is linearly moved in the 4 th direction (the direction indicated by the arrow V in fig. 13) which is the direction opposite to the 3 rd direction by receiving the pressing force from the protrusion 104.
However, in such a configuration, when the rotary member 102 rotates in either of the 1 st direction and the 2 nd direction, the protrusion 104 of the rotary member 102 receives an alternating load from the groove 108. Therefore, there is a problem that the durability (for example, durability of a broken life) of the protrusion 104 of the rotary member 102 is reduced.
In contrast, in the motion conversion mechanism 32 of the input device 2 according to the embodiment, the convex portion 48 of the moving element 30 is formed to be inclined with respect to the predetermined rotation axis 34 and is disposed between the 1 st projection 50 and the 2 nd projection 52 of the rotary member 26. Thus, when the rotary member 26 is rotated in the 1 st direction, the 1 st projection 50 presses the convex portion 48, and the mover 30 moves in the 3 rd direction. At this time, the 1 st projection 50 receives the load from the convex portion 48, but the 2 nd projection 52 does not receive the load from the convex portion 48.
On the other hand, when the rotating member 26 is rotated in the 2 nd direction, the 2 nd protrusion 52 presses the convex portion 48, and the mover 30 moves in the 4 th direction. At this time, the 2 nd projection 52 receives the load from the convex portion 48, but the 1 st projection 50 does not receive the load from the convex portion 48.
Therefore, only either one of the 1 st projection 50 and the 2 nd projection 52 receives the load from the convex portion 48 according to the rotation direction of the rotary member 26, and therefore the durability (for example, durability of the breakage life) of the rotary member 26 can be improved.
Further, the distance between the 1 st projection 50 and the 2 nd projection 52 varies with the rotation of the rotating member 26 when viewed from the projecting direction (Z-axis direction) of the convex portion 48. Specifically, when viewed from the protruding direction of the convex portion 48, the distance between the 1 st projection 50 and the 2 nd projection 52 is largest when the rotational position of the rotary member 26 is located at the center of the rotational range, and gradually decreases as the rotational position of the rotary member 26 moves toward both ends of the rotational range. Therefore, as described above, by forming both end portions of the convex portion 48 to be tapered, the 1 st projection 50 and the 2 nd projection 52 can be stably slid on the convex portion 48 from one end portion to the other end portion of the convex portion 48. As a result, the movable region of the rotary member 26 can be increased.
Further, the 1 st projection 50 and the 2 nd projection 52 draw an arc-shaped trajectory along with the rotation of the rotary member 26. Thus, as described above, by gradually decreasing the projection length of the convex portion 48 from the central portion of the convex portion 48 toward the both end portions, the 1 st projection 50 and the 2 nd projection 52 can be stably slid on the convex portion 48 from the one end portion to the other end portion of the convex portion 48. As a result, the movable region of the rotary member 26 can be increased.
